Aimlroles; New York (NY); Hybrid; USD 186.000 - 267.000; Vollzeit

Zusammenfassung

Formation Bio is seeking a Senior or Principal Data Scientist for the EHR AI team to build models using real-world data (EHR, claims, notes, imaging, and biobank-scale data). You will predict disease progression and treatment response, turning results into real-world evidence that informs drug acquisition and trial design.

This hands-on role requires training models, defining cohorts, and communicating results to Business Development and R&D within a hybrid NYC/Boston environment.

Qualifikationen

• PhD in computer science, biomedical informatics, statistics, epidemiology, or related quantitative field (required).
• 2+ years of industry or research experience building ML models on EHR data with real-world data; demonstrated results.
• Strong Python and deep learning expertise; familiarity with data lakes and distributed compute for large clinical data sets.
• High comfort with LLMs, including coding agents, as part of daily work.
• Knowledge of EHR data structures, clinical vocabularies, and OMOP CDM; experience with ICD-10, SNOMED CT, LOINC, RxNorm.
• Ability to explain technical results clearly to scientific and non-technical stakeholders.

Aufgaben

• Build, train, and validate predictive models on longitudinal EHR and claims data.
• Benchmark EHR foundation models for patient representation against baselines.
• Define and validate computable phenotypes and cohorts using OMOP CDM and vocabularies.
• Apply causal methods such as target trial emulation alongside predictive models.
• Answer EHR/RWE questions from Business Development and R&D on timelines with clear uncertainty statements.
• Write reproducible, reviewed code and collaborate with Engineering and Product.
• Principal level: lead a modeling workstream end to end and mentor other scientists.

About Formation Bio

Formation Bio is a tech and AI driven pharma company differentiated by radically more efficient drug development.

Advancements in AI and drug discovery are creating more candidate drugs than the industry can progress because of the high cost and time of clinical trials. Recognizing that this development bottleneck may ultimately limit the number of new medicines that can reach patients, Formation Bio, founded in 2016 as TrialSpark Inc., has built technology platforms, processes, and capabilities to accelerate all aspects of drug development and clinical trials. Formation Bio partners, acquires, or in-licenses drugs from pharma companies, research organizations, and biotechs to develop programs past clinical proof of concept and beyond, ultimately helping to bring new medicines to patients. The company is backed by investors across pharma and tech, including a16z, Sequoia, Sanofi, Thrive Capital, John Doerr, Spark Capital, SV Angel Growth, and others.

At Formation Bio, our values are the driving force behind our mission to revolutionize the pharma industry. Every team and individual at the company shares these same values, and every team and individual plays a key part in our mission to bring new treatments to patients faster and more efficiently.

About the Position

As a Senior or Principal Data Scientist on the EHR AI team at Formation Bio, you will build the models that let us learn from real-world data (RWD): electronic health records (EHR) together with claims and other real-world sources. You will work hands-on with longitudinal EHR and claims data to predict how disease progresses, how patients respond to treatment, and which approved drugs change the course of disease. The data spans large-scale, longitudinal EHR from health systems, linked to claims, clinical notes, and imaging, alongside biobank-scale genetic and molecular data. Your results become real-world evidence (RWE) that feeds directly into which drugs we acquire, which indications we pursue, and how we design trials.

This is a hands-on modeling role. You will train and evaluate models, including EHR foundation models, define the cohorts and phenotypes they depend on, and turn results into clear answers for Business Development and R&D, often on tight timelines. On the technology side, you will work closely with Engineering and Product. At the Principal level, you will also lead a workstream end to end and mentor other scientists.

Responsibilities

• Build, train, and validate predictive models on longitudinal EHR and claims data: disease progression, time-to-event outcomes, and patient-level treatment response
• Benchmark and adapt EHR foundation models for patient representation against strong tabular and sequence baselines
• Define and validate computable phenotypes and cohorts using the OMOP CDM and standard vocabularies, including features derived from clinical notes
• Apply causal methods such as target trial emulation alongside predictive models to surface drugs that modify disease course
• Answer EHR and RWE questions from Business Development diligence and R&D programs on days-to-weeks timelines, with explicit statements of uncertainty and bias
• Write reproducible, reviewed code and work with Engineering and Product to turn prototypes into reusable tools
• Principal level: lead a modeling workstream end to end, set its technical direction, and mentor other scientists

About You

Required Qualifications

• PhD in computer science, biomedical informatics, statistics, epidemiology, or a related quantitative field (required)
• 2+ years of industry or research experience building machine learning models on EHR data, including linked claims or other real-world data, with substantiated results: peer-reviewed publications, deployed models, or externally validated performance
• Strong Python and deep learning expertise, and familiarity with data lakes and distributed compute for large clinical datasets
• High comfort with LLMs, including coding agents, as part of your daily work
• Working knowledge of how EHR and claims data are generated and structured: encounters, diagnoses, procedures, medications, labs, vitals, clinical notes, coverage periods, and reimbursement records, along with coding practices, missingness, and variation across sites, payers, and countries
• Fluency with clinical vocabularies and common data models, including ICD-10 and its national modifications, SNOMED CT, LOINC, RxNorm, ATC, procedure coding systems, and the OMOP CDM
• Familiarity with common uses of EHR data and RWE in drug development: phenotyping and cohort definition, trial feasibility and eligibility, natural history, outcome prediction, external control arms, comparative effectiveness, and safety signal detection
• Rigorous evaluation habits: temporal and site-held-out validation, calibration, handling of censoring, and prevention of label leakage
• Ability to explain technical results clearly to scientific and non-technical stakeholders

Preferred Qualifications

• Experience pretraining, fine-tuning, or rigorously benchmarking EHR foundation models or LLM-based approaches to patient timelines
• Causal inference on observational health data: target trial emulation, propensity score methods, instrumental variables, doubly robust or ML-based estimators
• Use of LLMs for clinical text, such as phenotyping or information extraction from clinical notes
• Experience with OHDSI tools and network studies, or with large linked EHR and biobank resources (e.g., All of Us, UK Biobank)
• Experience in pharma, biotech, or health tech applying EHR models to drug development questions
• Exposure to health economics and outcomes research (HEOR)
